PUMP., y

Application filed January 20, 1913. Serial No. 743,195.

To .all whom-.it may Vconcern f Be it known thatI, .RICHARD E. K LrNn, a citizen of the UnitedStates, yresiding at Los Angeles, .State of California, have 'inventedv new and useful Improvementsin Pumps,y .of

solid matter inthe form of finelyxdivided suspended particles. `The'muddywater is run :throughditches and. into a sumphole, allowing .the larger' part'`the heavier `portions, .of thesolidvmatter to settle. The wa. ter is .then lpumped. back kthrough .the well;

but-it is neither practicable nor .desirable to have the water perfectly clean. It is this on the circulating pumps. l

My invention seeks to uobviate the inconunclean water which causes very hard wear venience of having to constantly and re-Y peatedly replace the wearing parts vof the pump piston.

My invention consists fundamentally in the provisionof a suitable packing means on the pump piston capable of gradual eX- pansion by adjustment from time to time.

The preferred form includes an expansible split sleeve, around which the packing is arranged; in combination with an easily operated means for expanding the sleeve. I provide that the expansive adjustment may be effected by the removal of a small cover plate on the cylinder head and by the adjustment of a single screw and lock nut. Complete renewal is needed only at long intervalsmany times the life of the arrangement outwardly in use.

I have shown a preferred form of my invention in the accompanying drawings, in which:

Figure 1 is a longitudinal central section showing my invention and its application. Fig. 2 is a cross section taken on two different planes, as indicated by line 2 2 of' Fig. l. Fig. 3 is a perspective showinga modified means for eXpandi-ngth'e split sleeve.

In the drawings, 10'designates any ordinary cylinder which may have a cylinder head 11 preferably provided with a small Specification of Letters Patent. y

opening l2'and .a-coverplate 13. .l Whenever it .is desiredzto adjust rthe pistonl-` packing,l this Cover ,plate L13 :is .only required Lto be ire.- moved thus obviating the inconvenience @of removing. .the v.wholev cylinder head. My improved piston is mounted upon th. piston rod "141; this red-having aportion 14 which is eXteriorly .tapered and lhas a cene,` trallongitudinal bore 15.y Uponathe :tapered portion of the rodthere is mountedamem4 ber 16, Consisting in a fsleewe` 17 `and an end disk orheacl V1.8. Another .end .disk or head' 19. is :mounted at the end of they-sleeve v17v the sleevel7 becoming a `spacer between the= two heads. -A `nut 20' holds all these parts on the rod portionlll. Theihead 118 is inte-1A gral with the .sleeve 17 .1;1 and the head 19 fits. on the portion/14:a ,of piston. rod 14 `-against sleeve 17,. .Thisuconstruction provides :for easy removal and renewal of .the heads with``r outuremoval .of the .other parte; and also; provides `for standandization .of parts -of the. piston.

In the .space between .the two piston heads 18 and 1.9. and around the sleeve 1:7 Althene is; arranged van .eXpansible sleeve 20 Y'pneferably composed of'a plurality of segments `21 of any suitablenumber. Each of these seg.-

.ments is mounted uponv guide rods 22;, the? guide rods projecting radially through .the sleeve 17. l.and through `thezpiston rod 14 and into the interior bore :15..of the. rod vThe p acln'ng 2.5 is .of any :suitable character Vand quality, preferably square yinucross sections, arranged in .a number .of ,cincles with lbuttedqends around ythe. `.eXpansibl-ey sleeve 20,. The breaks in :the packing y.at .the butted .ends are farnangedysoas to notxcome opposite each other. The packing is placed around the piston. constructie-rr' and Athepis-y y=ton-l1eads 18 and 19 are then forced toward each other to compress the packing between them, thus making a liquid tight mass of packing'betw'een the two heads. The size of the packing when new is such that it will engage the cylinder walls with the expansible sleeve 20 in its contracted position.

Aswear takes place on the packing, the segments lof the expansible sleeve are moved radially outwardly by a means acting upon the inner. ends of theguide rods 22. This means comprises a member 30 having thereon two wedge portions 31 engaging with the guide rods 22. The member 30 is of such size as to t in the bore 15; and its longitudinal movement in the bore will cause or allow the movement of the guide rods 22.

Movement of member 30 to the right in Fig. 1 will cause outward movement of the guide rods and cause expansion of the sleeve 2O and of the packing, keeping the packing always truly circular and in good contact with the cylinder. Movement of member 30 is accomplished by means of a screw 32 cooperating with the screw threaded portion 33 of bore 15. The outer end of the screw 32 has a square wrench opening 34; and a lock nut 35 sufces to hold the screw in any desired position. This lock nut also overhangs the nut 20 and locks it securely in position.

The wedge member 30 may either be circular in cross section, as is illustrated in Fig. 1, or may be square as is shown in Fig. 3. The circular wedge member may or may not be swivelly attached to the adjusting screw 32; but the square wedge member will be attached only by swivel. The square member has the advantage that the engagement of the ends of rods 22 with its wedge faces prevent its rotation; but, on the other hand, the circular wedge member is more easily manufactured and is very efficient in use.

With my construction, wear on the piston packing may be taken up from time to time by the simple and quick operation of adjusting the screw 32. For this purpose it is only necessary to remove the cover plate 13, loosen the lock nut 35 and then turn the screw 32 as much as desired. A slight adjustment from time to time suiices to keep the piston in working order; and it is only after the packing 25 is completely worn out that it becomes necessary to loosen the piston head 19 and renew the packing. Even this renewal is easily slid out of the cylinder as the packing is put into place.

As hereinbefore sta-ted, my invention is particularly adapted for use where the liquid to be pumped contains abrasive matter which causes great wear on the piston. Although I have devised my invention with a view to providing a circulating pump for Copies of this patent may be obtained for tions and conditions.

rotary drilling rigs, I do not wish to limit myself to this particular use; nor do I wish to limit myself to the specific details herein described, reserving the right to make such minor changes as may appear advantageous to adapt my invention to various combina The feature I wish to particularly emphasize is the use of the hollow piston rod with the expanding means arranged around and within it.

I have shown a coil of spring 5() which surrounds the members 20 for the purpose of bringing the members back to their normal position when the device is contracted. This spring is comparatively small and in no way interferes with the packing placed overv it.

Having described my invention I claim:

In combination with a cylinder, a piston rod having a longitudinal bore leading from one end, a piston on said end of the piston rod comprising a pair of heads, a sleeve inn tegral with one of the heads fitting around the piston rod and between the heads and forming a spacer between them, the sleeve and its attached head having a taper lit on the piston rod, a nut on the end of the piston rod to hold the two heads and the sleeve on the rod, a plurality of loose cylindrical segments around the sleeve between the two heads, guide rods attached to each segment projecting inwardly through the sleeve and the piston rod into the longitudinal bore thereof, a spring surrounding the segments to contract them, eXpansible packing surrounding the spring and segments between the two heads, a longitudinal slidable wedge member in the bore of the piston rod, a bolt screw threaded into the end of the piston rod connected to the wedge member, and means to lock saidbolt in any set position, substantially as described.

In witness that I claim the foregoing I have hereunto subscribed my name this 4th day of January, 1913.
